Description
Unsupported LdapConnection.SessionOptions throws LdapException with Message "The LDAP server is unavailable" on Linux. This is very misleading.
Reproduction Steps
Run this Code:
var ldapDirectoryIdentifier = new LdapDirectoryIdentifier("server", 389);
using var conn = new LdapConnection(ldapDirectoryIdentifier);
conn.SessionOptions.AutoReconnect = true;
Expected behavior
A PlatformNotSupportedExeption or NotImplementedExeption must be thrown. When getting just return null or an empty string if possible.
Actual behavior
On set or get on an unsupported property LdapException with message "The LDAP server is unavailable" is thrown on Linux. See Quick Watch below
